Web app developer Sencha has profiled Samsung's Android-based Galaxy Tab in comparison to Apple's iPad, concluding that while it is billed as "the first mass-market Android tablet; unfortunately, its a little bit of a disappointment."

Sencha develops JavaScript frameworks to enable developers to create apps--including rich multitouch mobile apps for iOS and Android devices--built from web standards. The company is therefore intently interested in how well new products support HTML5 and its related web standards, including advanced CSS3 transforms, SVG, Canvas animations, Web Sockets, embedded multimedia playback, and overall JavaScript performance.

In its developer scorecard of the Galaxy Tab, Sencha examined how well the new Android tablet performs compared to the iPad across a series of benchmarks including Acid3 (basic web standards), Modernizr (HTML5 feature support) SunSpider (JavaScript performance) and some real world testing.

Acid3 vs Android 2.2: where's the modern Webkit browser?

The Galaxy Tab runs a fairly stock version of Android OS 2.2, scoring 93/100 on Acid3, Sencha reports. This compares to a perfect 100/100 score on the iPad as well as RIM's BackBerry Torch, which Sencha also recently profiled.

Android lost points in Acid3 related to a Media Query test, but most of the points were deducted for failing SVG feature checks, as Android doesn't ship with support for the standard.

In its look at the BlackBerry Torch smartphone, Sencha reported that "Webkit based browsers have been shipping with a score of 100/100 for about a year now, so the result here would tell us how recently the BlackBerry team took their branch of Webkit. And the result is: 100/100. The Torch browser is running a modern Webkit browser."

Modernizr HTML5 features

The second test Sencha reviewed, Modernizr, is a JavaScript library written by Faruk Ates and Paul Irish which profiles compliance with a variety of HTML5 features.

While the Galaxy Tab supports a variety of modern HTML5 features, including localStorage, geolocation, CSS3 styles, Canvas, WebSQL, and drag & drop, it lacks support for features that work on the iPad, including CSS3 3D transforms, SVG, and Web Sockets.

Neither the Tab nor iPad support every component of HTML5, with both lacking support for Web Workers, WebGL, inline SVG and IndexedDB.

SunSpider JavaScript performance

In August, Sencha profiled SunSpider JavaScript scores across three generations of iPhone (3G, 3GS, and 4) running iOS 4.0, along with the BlackBerry Torch 9800 and two versions of Android: a Samsung phone running OS 2.1 and a Nexus One running 2.2 Froyo.

It discovered the Torch offered performance comparable to the iPhone 3GS or Android 2.1, while the Android 2.2 led in performance across the bar, being both good at text processing functions as well as math. In testing the Tab, Sencha reported identical performance, while an iPad running iOS 4.2 reported scores ranging from a few times slower to much slower (in the case of regular expression handling).

Sencha notes, however, that the benchmarks don't tell the whole story because they only test JavaScript performance as it runs on the CPU. "It doesnt account for the fact that Apple offloads lots of tasks to the GPU for better performance, so a comparison isnt entirely fair," the company wrote.

The real world web

One real world performance test Sencha created compares the rendering of sample ads created in both Flash and CSS3. Unlike the iPad and other iOS devices, which can only render the web standard CSS versions, Sencha reports that the Galaxy Tab can draw both.

"Sadly the performance of both Flash and CSS3 Ads are sub-par," Sencha said of the Tab's rendering. "Unlike the iPad, the Galaxy Tab does not use GPU acceleration for animation, so CSS3 Animations are quite choppy. Whats more surprising is the sub-par Flash experience. Flash font rendering is pixelated to the point of being unreadable. And when the page is scrolled, the Flash Ads jiggle up and down as the browser tries to re-position Flash content to catch up to the page movement."

A second test, created by Sencha Animator and focusing on advanced CSS3 animations, didn't render correctly on the Galaxy Tab. That was expected because the Modernizr test indicated its browser couldn't handle CSS3 transforms. However, the Tab also had problems loading WebFonts, another HTML5 feature it was expected to support.

Sencha skipped its SVG tests, given that Android doesn't include support at all, and proceeded to test real world applications using Canvas. One example worked, while another didn't. "No dynamic Canvas on the Galaxy," Sencha reported.

Next, in a test of embedded HTML5 web audio and videos, the Galaxy Tab again failed. "Neither [audio nor video] seems to work as embedded content, although it does seem that an HTML5 video will play via the native video player in full-screen view," Sencha wrote.

In a final "Sencha Touch Kitchen Sink" test, the firm observed that while most of of the interface components work on the Galaxy Tab, "the smoothness of both animations and scrolling isnt as accomplished as the iPad. GPU acceleration for CSS3 transforms is a significant area of catch-up for the Android team."

"One of the oddest aspects of the Galaxy Tab browser," Sencha reports, "is its CSS pixel to device pixel ratio. When queried in landscape mode, the Galaxy reports a screen.width of 683px and screen.height of 334px. Since the actual device resolution offers 1024×600, its giving us a 1.5× ratio of device to CSS pixels. This is a little bit of an odd choice since there shouldnt be any reason why it cant offer a 1:1 device-to-CSS-pixel ratio (or even just match the iPhone/Nexus One convention of a 320 pixel device.width which would give it a 1.875 ratio). This makes the Galaxy slightly bigger than a regular phone screen in CSS pixels, but not really big enough to handle what people want to put in a tablet screen."

The firm concluded, "the practical effect of this decision is that the Galaxy Tab is effectively an 'over-sized phone' for the purposes of web content. For example, an iPad-style side-navigation section just wont fit on the screen. We think its probably best to treat it as a phone with big pixels rather than a true tablet."

One problem with using Android 2.2 for tablets, Sencha explained, was that "when the Android browser gets ready to animate anything whether its a CSS animation or a plain old page scroll it shifts from high-quality to low-quality display mode. In low-quality mode, it turns off anti-aliasing (presumably on the theory that since things are moving, you wont notice the quality degradation.) This would be less noticeable on a smaller device. But on the 7″ Galaxy Tab, the resulting pixelation is striking, particularly since it switches to low-quality mode as soon as it detects a touch start event (but before anything moves)."

"Were still waiting for the first awesome Android tablet," the report observed.

The problem with these articles is Daniel Eran Dilger in previous articles has twisted the truth and written blatantly one sided articles attacking anything not by Apple so often I now automatically assume the opposite. It is like the boy who cried wolf.

Now I'm not planning on replacing my iPad with the Tab (or any of the honeycomb tablets coming next year), but if the Galaxy tab warrants a "html5 is not as good as the iPad" story, I immediately assume that overall the Tab must actually be pretty good and a legitimate competitor to the iPad or Daniel Eran Dilger wouldn't have bothered writing this piece.

Google's current Android for tablets is some really miserable crap, that's for sure. Of course, the also-rans like Samsung went ahead and released it anyway, looking like complete retards in the process. Sometimes it seems like the divisions of these companies that compete directly with Apple (or that were conceived for the explicit purpose thereof) are failing deliberately! Then again, when you whore out your OS to anyone that can slam together a box, what can you really expect?

Competing with Apple on quality, elegance, and innovation is nearly always a losing battle, even at the best of times. By comparison, most products feel awkward and substandard.

Google's OS/software offerings lack polish. A lot of them feel like slipshod betas with horribly unintuitive UIs. Lots to work on of they want Chrome to be an exemplar of superior User Experience. Then again, they could use their current approach and just flood the market with a lot of mediocre tech that likes to mimic Apple products. THAT strategy seems to be working, although it's ridiculously lame.

The problem with Orlando's comments is that he never makes a valid point, and instead chooses to simply make personal attacks that avoid any facts.

So when Orlando comments on a Dan article, I can ignore his comments as worthless trolling.

Especially when this article is pretty much just summarizing the findings of Sencha, which are linked in the article for independent reading, and doesn't inject the kind of "truth twisting" that trolls like Orlando are dashing to add to the comments.

Then I suggest that you simply stop reading anything with Dan's byline. Then you wouldn't get your tighty-whiteys all tied in knots.

I think he makes a point. DED isn’t impartial in his writings. For instance he says the iPhone gets a “perfect 100/100 [Acid3] score on the iPad” while I suppose it could be argued that 100 of 100 means perfect, for the Acid3 test perfect has another meaning, that is pixel perfect rendering which WebKit’s iOS has not yet achieved. It can’t pass the test without it, as well as completing it within a set timeframe not yet achievable on ARM’s low-power HW.

Overall, It’s a minor point and I don’t think having a passing score versus a 100/100 score or a score in the 90s doesn’t mean anything in the real world. By that same token, Google’s V8 JS engine is faster than WebKit’s but it’s not enough to make any defining difference in the user experience so it all comes down to which browser (or in this case mobile OS) you prefer.

Dick Applebaum on whether the iPad is a personal computer: "BTW, I am posting this from my iPad pc while sitting on the throne... personal enough for you?"

When Google warned companies such as Samsung NOT to use this year's versions of Android for Tablets, you have to wonder what Samsung's motivation was in doing just that. Of course, Samsung are a strongly Windows oriented company. Newsclips of their research centre, of their factor and offices shows a huge Windows love in pervades the whole company.

So, why launch an inferior Android Tablet before there is a suitable Android Tablet OS? Why launch a Tablet half as big as an iPad? Why charge the same as an iPad that beats it on so many counts?

You have to ask, is Samsung secretly hoping to damage the public view of Android Tablets so that, just as with Netbooks, they end up using Windows instead? Could it be that Samsung are more interested in selling preparing the ground for later Microsoft W7M based Tablets so they can dip their fingers into the glistening MS mobile devices marketing budget?

What if everything else, when compared to Apple's products, falls short, in his opinion?

Then he's telling the truth. And, if he knows what he's talking about, maybe his advice should be listened to.

No real need for advanced conspiracy theories... Samsung is the biggest conglomerate in one one of the world's most tech/gadget crazy and technically advanced nations. If there is a new trend, they have to offer something. It is that easy. Bada is not there yet, Windows has nothing for tablets and everything else can't be licensed. So, what should they do? Sell the iPad, like HP sold iPods? A 7" tablet with Android 2.2 makes no sense, as it is only a glorified media player at three times the price of an Archos device, but it is still better than saying: oops, we've got nothing. They managed to sell 1 million of these at quite a lunatic price, most of them in Korea I assume. That makes them the only competitor to Apple in tablets at this point. Stupid? Well, HP paid billions for Palm and has nothing. RIM has a Playbook video. MS has a Courier video. Samsung has 1 million sales, inferior or not...

Yea, the Galaxy tab sucks that's why it sold 1 million in a month and still going. Poor Apple fanboys there world is coming to an end. Hey Jobs "Android" LOL, I know that word scares him.

Just numbers alone mean nothing. It just shows how moronic some tech companies and some people are. An overpriced and undersized tablet with an operating system that was designed for phones. A wonderful experience right? Do me a favour and stop smoking.

He didn't make any point at all and after reading your post a couple of times I'm still not sure what your point is...

1 million people need to get their head checked. They got hosed. That figure's about right for how many units you can pinch off and push out to consumers before they wake up to the reality that it's just another subpar Apple device knockoff.

In any case, in its current form this lousy effort by Samsung (similar to H-Pee's) is done. Hopefully the next OS attempt by Google will suck a little less. But by then we'll have a new iPad, so none of this would have really mattered.

iPad cant run flash, so says over lord jobs. Hey jobs maybe you can put Android on your next iPhone, maybe sales will pick up. LOL

If you read the article, you realize that the Galaxy Tab doesn't run Flash well enough to matter either.

So Apple could have spent its resources trying to work with Adobe to deliver a Flash Player for iOS, sacrificing other features that are more useful and more likely to sell hardware, or it could have held up the iPad launch to wait around for Flash to ready itself, and either way given users a device that ran desktop-oriendted Flash content really poorly, inefficiently, and in a way that looks ugly, consumes the battery, and prevents users from ever getting open HTML5 content.

Or we could have the situation we have now, where the rampant success of the iOS is making Flash irrelevant in mobile devices and everyone is rushing to HTML5 for dynamic content and multimedia delivery.

I prefer what Apple decided to do. Sure, there are Flash things I'd like to be able to access, but they really aren't that important. Ridding the Web of Flash is preferable to playing back that content poorly, as Google is doing on Android devices.

Just to add something of relevance to my comments, I am sure I've read that while the iPad scores 100/100, it's not a 'perfect' pass as Bilger puts it. The rendering also has to be perfect. Apparently, this is not the case according to the Playbook v iPad comparison put forth by RIM.

I don't have an iPad so I can't comment on this but there are other things about the article that irritate me, the primary one being the suggestion in the headline that the linked article pits the iPad against the Galaxy Tab. It most assuredly does not. It is for these reasons that I take everything Dilger writes with a healthy grain of Na.

Taken from Computerworld, Matt Hamblen on 6 Dec:
"Samsung has sold 1 million Galaxy Tab tablet devices worldwide just two months after putting it on sale outside the U.S., and all four major wireless U.S. carriers starting sales in mid-November.

The larger 9.7-inch screen Apple iPad tablet hit the 1 million sold mark just one month after going on sale in April.

The Thanksgiving holiday likely helped spur sales in the US, although Samsung has not revealed sales figures for specific regions. A Samsung spokeswoman did confirm to eWeek magazine that it had reached the 1 million sales mark globally."

While the Tab has reached a milestone, it is doing so at a time when we typically see spikes in tech sales. The Tab is still relatively new and has an unknown reliability track sheet, not to mention we don't know how many people have returned "sold" Tabs. I would expect to see the spike in sales continue through mid-Jan, then fall once the iPad 2 and Playbook announce actual release dates between Mar and Apr.

If the Tab can maintain selling 500,000 units per month at the end of Q1 2011, then I think it can be considered a success.

I disagree. I think Flash on the iPad is great. There is no disappointment. Zero expectations, zero surprises. I have it in mind to use other ways of watching video, i.e. HTML5 or site-specific apps like the Youtube app.

With the Tab and every other Android device so far, you may expect to get Flash capability when you buy the device, but what you end up getting is a hobbled bunch of junk that works choppily half the time and not at all the rest of the time.

iPad wins in terms of Flash. There's no distortion of the facts there. A half-assed solution that is effectively useless is not a solution at all. It's far better not to make promises you can't keep.

I just wasted my time looking at some internet dude's posting history, and noticed that he always uses "there" instead of "their." Of course, everyone can type the wrong word from time to time and it's no worse than a minor distraction, but when you do it every time it gets really irritating.

Also, the Tab sold a million in two months, though I don't suppose there's much value in pointing that out to such a poster. Really, I just can't take the misuse of the possessive adjective. I know, I know, it's rife on message boards, especially amongst trolls, but I'm afraid that someday it will become such a widespread mistake that no one remembers how to do it right. See also "could care less" instead of "couldn't care less" as well as using "begs the question" as to mean "suggests the question" rather than to refer specifically to the logical fallacy of assuming the truth of a proposition when arguing for it.

In conclusion, some internet dude, please stop destroying English. It's a wonderfully flexible, rich, and deep language, which I invite you to learn.

Sid is daharder. His first post always attacks Steve Jobs, followed by other crap. Please daharder (aka Sid) please tell why you post on this site ?

Let me say something about the tab. Someone, apple, comes out with a great Market defining product and for a long time in tech terms, no one has anything really remotely close to it in so many respects. Then samsung throws in the only alternative pretty much, of course it's going to sell some units, but so what? My first mp3 player was a samsung, it s the gadget I used less than any other... The tab is at best an also run.
